11.5.2 Installing a terminal block
1. Clip the connecting wires to the back of the terminal block, the clips are different
sizes and must be connected to their matching receptacle.
2. Connect the terminal block to the junction box housing by tightening the two
mounting screws. Install the divider with the two mounting screws if applicable.
3. Reconnect remote cabling, replace the junction box cover on the sensor, and
connect power.
11.6 Trims
LOI menu path Diagnostics → Trims
Trims are used to calibrate the transmitter, re-zero the transmitter, and calibrate the
transmitter with another manufacturer's sensor. Proceed with caution whenever
performing a trim function.
11.6.1
D/A trim
LOI menu path Diagnostics → Trims → D/A Trim
The D/A trim is used to calibrate the 4-20mA analog loop output from the transmitter. For
maximum accuracy, the analog output should be trimmed for your system loop. Use the
following steps to complete the output trim function.
1. Set the loop to manual, if necessary.
2. Connect a precision ammeter in the 4-20mA loop.
3. Initiate the D/A trim function with the LOI.
4. Enter the 4mA meter value when prompted.
5. Enter the 20mA meter value when prompted.
6. Return the loop to automatic control, if necessary.
The 4-20mA trim is now complete. The D/A trim can be repeated to check the results.
Alternatively, the analog output test can also be used to verify loop performance.
